Eeswaran is a 2021 Indian Tamil-language action drama film directed by Suseenthiran and produced by Balaji Kapa under Madhav Media.

The film stars Silambarsan in the titular role, alongside Bharathiraja, Nidhhi Agerwal (in her Tamil debut) and Nandita Swetha.

In March 2020, the Indian government imposed a COVID-19-related lockdown, and Periyasamy's family chose to move to the village rather than remain in the city.

Periyasamy rejoices at the idea of spending more time with his grandchildren, so he calls astrologer Kaali, who predicts that there will certainly be a death in the next few days, leaving them worried about contracting the coronavirus and dying from the complications.

However, the doctor informs Eeswaran about Periyasamy's young granddaughter Diya's rare heart condition, which requires immediate attention.

Periyasamy's daughter and son-in-law Maragadhamani's business keeps incurring losses, and his wife's brothers lend him money, but he fails to repay them, leading to family feuds.

A source claimed that Simbu had read the script through a virtual meeting with the director, due to the COVID-19 lockdown, and expected to shoot the film in October 2020, during the fifth phase of unlock.

"[23] Ranjani Krishnakumar of Firstpost gave 1.5 out of 5 and stated "In bringing together this colourful and relatable cast of characters, Suseenthiran scores.

"[25] Manoj Kumar R of The Indian Express gave 1 out of 5 stars "Eeswaran is nothing but a two-hour-long verbal and visual flow of cues that reinforce the patriarchal view of women's subservient role to men in a family.

"[26] Logesh Balachandran of India Today gave 3.5 out of 5 and wrote "Eeswaran isn't a great film, but director Suseenthiran gets many things right.

At a time when fans are longing to witness that energetic Simbu on screen, which has been missing for years now, Suseenthiran delivers a perfect rural entertainer that serves just that.

"[27] In the motion poster of the film which was released on 26 October, the protagonist Silambarasan had a snake wrapped around his neck a forest official filed a case stating that the team had given sedatives to the animal to prevent it from harming the team which kills the animal very soon and also said that many crews are lying telling it is a fake snake.

[29][30] Director Suseendhiran was involved in controversy over unnecessarily interrupting when Nidhhi Agerwal was speaking in front of public during the audio launch of the film.

However, the Tamil Nadu Theatre Owners Association opposed the decision for a simultaneous OTT release, fearing that piracy sites may upload the high definition print of the film, which will affect the theatrical business.
